"Note that although this model is termed a "Gaussian chain", the distribution function is not a gaussian (normal) distribution. The end-to-end distance probability distribution function of a Gaussian chain is non-zero only for r > 0. [1]"

As article stands now, the above sentence obscures the reason why this model is termed a Gaussian chain. This model is called 'Gaussian' because the probability distribution function to any vector point does have a Gaussian form. i.e. $P({\vec {r}})\propto exp(-{\vec {r}}\cdot {\vec {r}}/2\sigma ^{2})$

However, the end-to-end distance distribution will depend on the dimensionality of the polymer chain. I think this point needs to be added so as to clarify why this is called a Gaussian Model- rather than misleadingly pointing out how the name might not be apt.

I find that sentence confusing and missing of a proper reference to state that. LudovicaAisa (talk) 21:17, 11 December 2023 (UTC)[reply]
